Guzmania plant named ‘G9518’

ABSTRACT

A new and distinct  Guzmania  cultivar named ‘G9518’ is disclosed, characterized by a very durable plant with a uniquely shaped inflorescence and white tipped flowers. The new variety is a  Guzmania,  typically produced as an indoor ornamental plant.

Latin name of the genus and species: Guzmania conifera×lingulata.

Variety denomination: ‘G9518’.

BACKGROUND OF THE INVENTION

The new cultivar is a product of a planned breeding program. The objectives of the planned breeding program were to develop new Guzmania varieties. The new variety originated from a cross pollination of the seed parent, unpatented Guzmania conifera×lingulata variety ‘Cardinalis’ and the pollen parent, the unpatented Guzmania lingulata variety ‘El Cope’. The crossing was made during September of 2002 in a commercial greenhouse in Alajuela, Costa Rica.

The new variety was discovered by the inventor, Chester Skotak Jr., in September of 2006 in a group of seedlings resulting from the crossing. The new cultivar was found in a commercial greenhouse in Alajuela, Costa Rica.

Asexual reproduction of the new cultivar ‘G9518’ was first performed at a commercial laboratory in Evergem, Belgium, by tissue culture on August of 2011. Subsequent propagation by tissue culture has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘G9518’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G9518’. These characteristics in combination distinguish ‘G9518’ as a new and distinct Guzmania cultivar:

-   -   1. Unique inflorescence shape.     -   2. Very durable plants, resistant to various environmental and         physical stressors.     -   3. White tipped flowers

PARENT COMPARISON

Plants of the new cultivar ‘G9518’ are similar to plants of the seed parent, the unpatented variety of Guzmania know as ‘Cardinalis’ in most horticultural characteristics, however, plants of the new cultivar ‘G9518’ produces different shaped inflorescence compared to that of the seed parent ‘Cardinalis’.

Plants of the new cultivar ‘G9518’ are similar to the pollen parent, the unpatented, variety of Guzmania know as ‘El Cope’ in most horticultural characteristics. However plants of the new cultivar ‘G9518’ produce a different flower shape compared to the flower shape of pollen parent ‘El Cope’, which is wider and rounder in shape. Additionally the leaves produced by the new cultivar ‘G9518’ are narrower and shinier than those of pollen parent ‘El cope’. Finally the leaves produced by the new cultivar ‘G9518’ are green on top and on the underside, whereas the leaves of pollen parent ‘El Cope’ are a darker red-brown on the underside.

COMMERCIAL COMPARISON

Pollen parent variety is the best commercial comparison known to the inventor.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘G9518’ grown in a greenhouse in Evergem, Belgium. This plant is approximately 18 months old, shown in an 11 cm. pot. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
